We wanted to move the trailer so I decided to use the one of the Speedex's instead of hooking up the truck. I felt the Gt would move it but I wasn't so sure the front wheels would stay on the ground as it lifted the front of the the trailer. Turned out to be no problem.

Think all in the Balance over the axles of the trailer. I can use my big PK to move my trailer, sometimes better if loaded some than is empty with big tongue weight. I can usually pull the trailer, it's the lifting with hydraulics that is hard on tractor or does not work because of weight.

Several years ago I worked at a place where we had to move a lot of trailers around the lot. We had a JD M with a bar mounted across the hitch with a ball mounted on each end so that the ball was near the outside edge of the wheels. This way you could look down the side of the trailer instead of staring at the front of it. Also by using the proper ball you could turn the trailer on the spot.
